Furthermore, the drawings are not 1: 1, and the relative dimensions of the various elements in the figures are drawn for illustration only and not necessarily to true scale.

In order to facilitate understanding of the technical solution of the present invention, before the detailed description, a method for improving the flatness of the LED display screen in the prior art is described first.

The LED display screen is a large-scale display formed by splicing a plurality of display units, specifically, the display units are composed of a plurality of LED lamp beads, a PCB substrate, a plurality of driving chips (including row driving chips, column driving chips and the like), the display screen box body is composed of a plurality of display units, a box body, a switching power supply (an AC-DC module or a DC-DC module) and a control system module, and the display screen box body is spliced to form the large-scale LED display screen.

As background art says, after a plurality of display units are spliced to form a display plane, a certain concave-convex deviation exists between the display units, that is, the flatness of the LED display screen, generally speaking, the flatness value (the better the flatness is, the smaller the flatness value is) of the LED display screen is within ± 1mm, the displayed image is not distorted, and a local bulge or a local depression may cause a dead angle in the visual angle of the display screen. Moreover, as the dot pitch of the LED display screen is smaller and the requirement for the display effect is higher and higher, the requirement for the flatness of the display screen is also higher and higher, for example, the flatness value of the indoor small-pitch LED display screen is usually controlled to be ± 0.15mm, and the flatness has become one of the key parameters for measuring the quality of the LED display screen.

Firstly, at the splicing position between the display units, the phenomenon of inconsistent distance may occur between the LED lamps at the edges of the adjacent display units, namely, a splicing gap is generated, the influence on the display effect is mainly shown as bright lines or dark lines when images are displayed, and when the distance between the points of the LED display screen is reduced, the problem is particularly prominent, and the display effect is seriously influenced; when the display screen is assembled, the two boxes are connected through connecting pieces such as screws and the like, so that the splicing gap of the display unit between the boxes is ensured, the installation of the connecting pieces such as the screws and the like is generally carried out on the side faces of the boxes, the installation and fine adjustment efficiency is very low, and long time is needed.

Secondly, the flatness of the LED display screen is also affected by the dimensional accuracy of each part formed by the display screen. The components forming the LED display screen are all inevitably subjected to certain processing errors and deformation, so that the flatness of the mounted LED display screen is influenced by the processing errors and the deformation of different degrees, and the unevenness of a display plane is a result of superposition of multiple errors and deformation.

In addition, the proficiency of installation workers also can influence the flatness of the LED display screen to a certain extent, and because the display screen is assembled, the display box body is often required to be adjusted on site according to actual concave-convex deviation among the display units, or the flatness is improved by adding the gasket, so that the working difficulty of the workers is improved, and long time is required to be consumed.

At present, to improve the flatness of the current LED display screen, there are mainly the following two ways:

1. the dimensional accuracy of the parts is improved. The processing precision of parts is guaranteed through improving production technology, the splicing precision of display screens is guaranteed through changing the high-strength material and strictly controlling the deformation of parts, but this undoubtedly can increase very big manufacturing cost.

2. And setting a display unit fine adjustment structure. Through setting up display element fine setting structure, when the display screen is assembled, finely tune display element, the roughness of improvement display screen that can be better, but this experience requirement to the staff is higher, and assembles the process that improves the roughness and need consume a large amount of time, and to a great extent has increased human cost and time cost.

Therefore, it is desirable to provide a box body, a box body composition and a display screen which can solve the problems of high cost and efficiency of the existing method for improving the flatness of the LED display screen.

In the embodiment of the present application, the leveling member includes three forms to accommodate leveling between the tank bodies 100 at different adjacent positions. For ease of understanding, three forms of leveling members are named a first leveling member 3204, a second leveling member 3205, and a third leveling member 3206.

The first leveling member 3204 is connected between the first portions 110 of two tank bodies 100 located on the outermost side of the tank assembly 300 and adjacent to each other in the width direction of the tank assembly 300, and the first leveling portion 3202a, the connecting portion 3202c, and the second leveling portion 3202b of the first leveling member 3204 are linearly arranged in the width direction of the tank assembly 300.

As shown in fig. 10 and 11, the second leveling member 3205 is connected between the first portions 110 of two tank bodies 100 located at the outermost side of the tank assembly 300 and adjacent to each other in the longitudinal direction of the tank assembly 300, the first leveling portion 3202a and the second leveling portion 3202b of the second leveling member 3205 are disposed opposite to each other in the longitudinal direction of the tank assembly 300, and the connecting portion 3202c is located at one end of the first leveling portion 3202a and the second leveling portion 3202 b. In this way, the first leveling part 3202a, the connecting part 3202c, and the second leveling part 3202b of the second leveling member 3205 can be combined to form a concave shape. It should be noted that the positions of the first leveling member 3204 and the second leveling member 3205 can be interchanged, and the corresponding leveling effect can be achieved.

As shown in fig. 12 and 13, the third leveling member 3206 is connected between the first portions 110 of four tank bodies 100 located inside the tank assembly 300 and arbitrarily adjacent in the width direction and the longitudinal direction of the tank assembly 300, the third leveling member 3206 includes two first leveling portions 3202a, two second leveling portions 3202b, and two connecting portions 3202c, one of the first leveling portions 3202a and one of the second leveling portions 3202b are disposed opposite to the other first leveling portion 3202a and the other second leveling portion 3202b along the width direction of the box assembly 300, the first leveling portion 3202a and the second leveling portion 3202b on either side of the width direction of the box assembly 300 are disposed opposite to each other along the longitudinal direction of the box assembly 300, each connecting portion 3202c is disposed at one end of a corresponding first leveling portion 3202a and a corresponding second leveling portion 3202b, and the two connecting portions 3202c are adjacent to each other.

Therefore, the positioning of the first leveling component 320 can be more reliable, and the leveling effect is more stable.

Specifically, the first leveling part 3202a and the second leveling part 3202b of the leveling member are both limited in the corresponding limiting groove 1104 of the first portion 110.

In some embodiments, the first portion 110 has a limiting protrusion 1105, a side of the limiting protrusion 1105 facing away from the second portion 120 in the first direction protrudes out of the first leveling surface 1101, the first leveling component 320 has a matching groove, and the matching groove matches with the limiting protrusion 1105, so that the first leveling component 320 is limited to the first portion 110 in a third direction, wherein the third direction is perpendicular to the first direction. Furthermore, the first direction, the second direction and the third direction are perpendicular to each other. Specifically, the third direction is a longitudinal direction of the case assembly 300.
